Final answer:
The three most common sources of research questions are the study of clinical problems, replication of prior research, and testing nursing theory.
Step-by-step explanation:
The three most common sources of research questions are:
- Study of clinical problems: Researchers often identify gaps in medical knowledge or areas of unmet clinical needs, which can lead to research questions.
- Replication of prior research: Researchers may aim to replicate existing studies to validate their findings or explore further.
- Testing nursing theory: Nursing researchers often develop research questions to test and refine nursing theories for better patient care.
